The rates of surgical site infection were significantly higher in patients with an injection prior to TKR than those without ( percent versus percent), as were the rates of infection requiring a return to the operating room ( percent versus 1 percent). The rate of infection requiring a return to the operating room remained significantly higher for the patients receiving injections in the months prior to surgery, with an odds ratio (OR) of for an injection within one month of surgery, and an OR of for an injection seven months prior to TKR.

Corticosteroid myopathy presents as weakness and wasting of the proximal limb and girdle muscles and is generally reversible following cessation of therapy.

Corticosteroids inhibit intestinal calcium absorption and increase urinary calcium excretion leading to bone resorption and bone loss. Bone loss of 3% over one year has been demonstrated with prednisolone 10 mg per day. Postmenopausal females are particularly at risk for loss of bone density. Sixteen percent of elderly patients treated with corticosteroids for 5 years may experience vertebral compression fractures. One author reported measurable bone loss over two years in women on concomitant therapy with prednisolone mg per day and tamoxifen . [ Ref ]

While the human body manufactures an endogenous Testosterone level in the range of 70mg/week, the Testosterone dosage required for physique and performance enhancement must sit well above that, with a minimum being in the range of 300 – 500mg per week for beginners, for example. Intermediate and/or experienced anabolic steroid users can venture even higher than that. In addition to the higher bodybuilding dosage, the injections must be administered much more frequently. While TRT patients can ‘get by’ with a single 250mg injection of Testosterone Enanthate once per week (or even once every two weeks as is commonly applied clinically), an athlete or bodybuilder would have to administer 250mg of Testosterone Enanthate twice per week (for a total of 500mg) in order to experience a steady onset of performance and physique enhancing benefits. This is very necessary due to a constant steady peak blood plasma level of the anabolic steroid that is necessary for constant biological action within muscle tissue in the body. Testosterone Enanthate, as mentioned earlier in this article, exhibits a half-life of 7 – 10 days, but although its half-life is 7 – 10 days, sharp declines in blood plasma levels begin to occur several days before the end of the half-life period. When performance and physique enhancement is desired, the administration of doses must occur more frequently in order to keep blood plasma levels elevated as best as possible. For medical purposes such as TRT, sharp spikes and peaks and valleys in blood plasma levels can be afforded (although it is still not optimal), as the patient is simply utilizing Testosterone to obtain normal physiological levels, and is therefore not particularly concerned with dramatic performance or physique changes on a weekly basis.

In fact, the anatomical studies have demonstrated that after the radicular medullary arteries enter the neuroforamen in the anterior aspect of exiting nerve root and dorsal root ganglion, they often travel a distance superiorly and laterally in the lateral epidural space to join the anterior spinal artery supplying the anterior two thirds of the spinal cord. Additionally, in about 63% of cases of cadaver studies, there is a posterior branch of the radicular medullary artery going to the dorsal aspect of the cauda equina. It is conceivable that the epidural needle in the interlaminar lumbar epidural steroid injection will very likely encounter the radicular medullar artery in the lateral aspect of the epidural space or midline posterior epidural space.
